Asymptomatic urethral gonorrhea among men in public New York City Social Hygiene Clinics.

Cultures were made from the urethra of 2,370 male Social Hygiene Clinic patients who were not directly associated with gonorrhea by signs, symptoms or epidemiology were cultured for N. gonorrhoeae. Of these asymptomatic individuals, 37 or 1.6% were found to be urethrally infected. Gram stain smear examinations of urethral specimens from these men were positive in about one-half of the cases.
